CT_system_1According to a new study, researchers mentioned that using a combination of computed tomography (CT), postmortem CT angiography (CTA), along with biopsy can be useful as a minimally invasive procedure for detecting the natural causes of mortality, such as cardiac arrest. The study took place at the Institute of Forensic Medicine, Center for Forensic Imaging and Virtopsy, at the University of Bern in Bern, Switzerland. The findings of the study appear in the November issue of the American Journal of Roentgenology.

It is noted that postmortem imaging, particularly CT, has been gaining more acceptance in forensic medicine practice for the last ten years. Yet, the technique has showed some limitations when it was used for detection the causes of natural death. Stephan A. Bolliger, MD, lead author of the study, said "Vascular and organ pathologic abnormalities, for example, generally cannot be visualized accurately using native CT scans. To address the problem of these abnormalities, postmortem angiography has been implemented with great success," During the study, researchers used CT, CTA and biopsy in a minimally invasive procedure to examine 20 bodies. A comparison was later made between the results obtained through that procedure and those obtained through autopsy. It was reported that the minimally invasive procedure had significantly more accurate results (18 out of 20 cases). Dr. Bolliger commented "The combination of CT, postmortem CTA and biopsy is a valid tool to examine bodies in a minimally invasive fashion. However, a close collaboration between pathologists and radiologists is imperative for the correct sampling and diagnostic assessment and, therefore, for the success of such an undertaking,"
